RE: lundahl par-pp output transformers your thoughts?

Lundahl uses a transformer geometry where windings are separated from each other on different sides of the core. That may work well for push pull but not single ended because the spacing causes a phase loop-d-loop in the 10-20Khz range. For SE an EI core is a better configuration since the windings are on top of each other and the phase issues are above the audible range.

Yes, this statement will cause a controversy.
